Semerjian, H G; Presser, C

The objective of this project is to investigate droplet evaporation, combustion and particulate formation processes in spray flames, using nonintrusive diagnostic techniques, and to delineate the effect of chemical and physical properties of liquid fuels on the above processes. During previous phases of this project, the design and fabrication of the variable swirl burner was completed, and the operating characteristics were evaluated over a wide range of operating conditions. Photography, high speed cinematography, and laser sheet beam scattering techniques were used to identify various regions of the spray flame, and to observe trajectories of large droplets and overall features of the flame. Complete data sets on a kerosene spray have also been obtained with both a pressure atomizer and an air-assist nozzle. 58 refs., 9 figs., 2 tabs.
